“…For example, in the Amazon about 95% deforestation has occurred within a 5.5 km buffer of road networks (Barber et al, 2014). The poorly located and functioning forest road (public or private roads exclusively for forestry – conservation, management and logging) can significantly alter water quality, wildlife, and causes significant soil loss and generates huge sediment from the road and its surroundings by changing slope stability, drainage pattern and overland flow (Misir et al, 2007; Nunamaker et al, 2007).…”

Transport network infrastructure interacts with the earth’s surface because they often share common spaces (e.g. river valleys), such that transport is an anthropogenic pressure that can affect geomorphological processes and outcomes. Since having its profound effect worldwide, the systematic study on the effect of transportation infrastructures (TIs) on the alteration of geomorphological forms and processes has been less focused than on any other anthropogeomorphic driver. The present review provides a multidimensional overview based on the available literature and data on the effect of TIs in changing hillslope and fluvial geomorphology to sustain a peaceful harmony between the transport network and its surrounding landscapes. The study underlines the effect of major TIs like trails, roads, railways, tunnels, causeways, waterways and airports on the alteration of different geomorphological processes on hillslope and fluvial landscapes like the movement of earth material, geomorphic connectivity, slope instability, sediment production, gully initiation and surface runoff. For instance, the global level proximity analysis shows ~40% of landslides happen within the 500 m of any major roads only, while at the regional scale it becomes ~65% irrespective of the degree of seismicity. Due to the fast development of TIs, the mountain regions are more prone to slope instability because of the alteration of surface hydrology by increasing runoff, road and ditch guided concentrated flow, rills and gully formation by reducing drainage area to cross the critical threshold limit. The plain regions are primarily facing the problem of fluvial (dis)connectivity because of the close proximity between river and transport networks and undersized causeways. For sustainable TIs development, factors like the practice of bio-engineering for roadside slope management, de-culverting, 100-year flood return for causeway construction, mapping of river corridors, road water harvesting should be incorporated for less effect on hillslope and fluvial geomorphology.

“…Within certain time and space, diversity is determined by the combination of abiotic constraints, biotic interactions, and disturbances (Frelich et al, 1998;Misir et al, 2007;Nagaraja et al, 2005;Spies & Turnier, 1999;Ucler et al, 2007). Abiotic factors, such as elevation, slope, aspect, soil texture, climate etc., specify the conditions of physical environment and thus the primary species distribution.…”

Forest Ecosystems-More than Just Trees 4 1.2 Structural diversity "Structural diversity refers to the physical organisation or pattern of a system, including the spatial patchwork of different physical conditions in a landscape, habitat mosaics, species assemblages of different plant and animal communities, and genetic composition of subpopulations" (Stokland et al., 2003). The main structural indicators that are used to describe the conditions for forest biodiversity include stand vertical structure, age class distribution and the amount of dead wood (Christensen et al., 2004). They represent an indirect approach "as they show, typically on a rather gross scale, how the house is built, but give no information on whether the inhabitants have moved in" (Christensen et al., 2004). 1.3 Functional diversity According to Noss (1990), function involves all ecological and evolutionary processes, including gene flow, disturbances, and nutrient cycling. "Functional diversity involves processes of temporal change, including disturbance events and subsequent succession, nutrient recycling, population dynamics within species, various forms of species interactions, and gene flow" (Stokland et al., 2003).

“…The Hyrcanian forests, which have survived the Cenozoic geology and the Ice Age due to the northern temperate climate in northern Iran, are a unique forest mass along the southern shores of the Caspian Sea, dating back to the Triassic period, which has been registered as Iran's second natural heritage in the UNESCO World Heritage List (Akhani et al 2010). These forests are spread in some parts of the ve provinces of Semnan, Golestan, Gilan, Mazandaran, and North Khorasan with an area of 1.9 million hectares (approximately 800 km long and 20 to 70 km wide) from Astara in the north of Gilan to Glidagh in the east of Golestan province (Akhani et al 2010; Sur ra 2019; Misir et al 2012). These forests have a very diverse fauna and ora.…”

The Hyrcanian forests have a diverse fauna and flora with many endemic species of plants and animals. Rana pseudodalmatina is one of the endemic species in this forest. The phylogenetic and morphologic analysis indicates the existence of the western and the eastern clades in R. pseudodalmatina. The life history of an organism comprises its growth, development, age, and reproduction. Differences in the life history of the same species can attributed to different habitat quality or climate. The probability of encountering a wood frog in the western half of the Hyrcanian forests of the southern shores of the Caspian Sea is much higher than in the forests of the eastern sea. This increase in the detection probability can attributed to higher precipitation levels in the west of the Caspian Sea compared to the east. We observed that the Eastern populations tend to have larger sizes. In addition, the individuals of the western branch have a lower mean age (5.29 ± 0.74 years) than the eastern ones (8.36 ± 0.08 years). According to our results, females were larger (54.64 ± 0.53 mm) and older (7.68 ± 0.24 years) than males (48.13 ± 0.39 mm; 5.89 ± 0.39 years) in both eastern and western clades. So, the difference has been attributed to the variation in precipitation between the east and west of the sea, leading to different living conditions for R. pseudodalmatina. Hence, any conservation planning to protect this native species of the Hyrcanian forests must consider inter and intra-population differences in the east and west of the Hyrcanian forests.
